Buttons don't work?

I have a baumatic bdw15 intergrated dishwasher. The overflow pump didn't stop, so I checked the internet and many forums said to remove the dishwasher and tilt it back 45 degrees allowing the water to drain out. I did this. Now I have re-installed the dishwasher and went to turn it back on again. The on/off button works, but none of the other buttons do anything. There is no error code displayed. If I lift the float up, the drain pump does still activate the pump to start again. Do I need to re-set this switch ??\r\n
Please help...
